Within this study, we propose a technique for MR thermometry close to metal. The technique utilizes a multispectral imaging approach and the temperature dependency of the T1 relaxation time. Within a phantom experiment, initial feasibility is demonstrated by tracking the T1 change close to a metal implant during heating.
